I think it was just cleverly subverting audience expectation for what he was about to say next, not an attempt to actually change language.

The change is due to proponents of current ai use having intelligence, but not actual intelligence. Small, but subtle difference.

I believe the term is "natural insemination"

Renaming a thing because of a new thing has been a part of the evolution of language forever.

With specific regard to "artificial" and your example...Just yesterday I saw the title of an article about Football FIelds: Grass vs Turf. So apparently the artificial kind is now just "turf." Luckily we already had "grass" as a synonym for actual turf. Although in some contexts we need to specify "actual grass" as opposed to cannabis.

Usually when an artificial item comes along, the original item is then described as "real." Real flowers, real vanilla, real diamond (a misnomer but still) real breasts, real Christmas tree...

But of course in this case they're looking for the initials to be A.I.
